Answers
Answer : AREA OF A CIRCLE = PIR2 ( PI ×R ×R )
N.B = R MEANS RADIUS.
GIVEN THE CIRCUMFERENCE, WE WILL USE THE CIRCUMFERENCE TO FIND THE RADIUS.
FORMULA FOR FINDING RADIUS = CIRCUMFERENCE ÷ 2 × 3.142.
SO THAT IS : 31.4 ÷ 6.284 = 4.9. ROUND UP : 5. SO THE RADIUS IS 5. NOW WE CAN FINDING THE AREA. 3.14×5×5 = 78.5 . Say thanks Nique.A rectangular room measures 15 feet by 18 feet. It is going to be carpeted with carpeting that sells for $38 per square foot.

foot high ceiling. How large an air conditioner would this room
Answers
Answer:
a. 270 square feet
b. 3.75 inches by 4.5 inches
c. $10,260
Step-by-step explanation:
A rectangular room measures 15 feet by 18 feet. It is going to be carpeted with carpeting that sells for $38 per square foot.
a. What is the area of the room in square feet?
Area of a rectangular room = Length × Width
Length = 15 feet
Width = 18 feet
Area of the room = 15 feet × 18 feet
= 270 square feet
b. If the room is drawn to 1/4 inch represents 1 foot scale, give the dimension of the room in inches on the scale drawing. Please write in decimal form to the nearest hundredth.
From the above question:
1/4 inch = 1 foot
Length = 15 feet
Hence:
1 foot = 1/4 inch
15 feet = x inch
Cross Multiply
x = 15 × 1/4 inch
x = 3.75 inches
For the Width = 18 feet
Hence:
1 foot = 1/4 inch
18 feet = x inch
Cross Multiply
x = 18 × 1/4 inch
x = 4.5 inches
Therefore, the dimensions of the room in inches is
3.75 inches by 4.5 inches
c. What is the total price for the carpeting? _
From the above question, we know that: A square foot of carpet is sold for $38
The area of the room is 270 square feet
Hence:
1 ft² = $38
270 ft² = $x
Cross Multiply
1ft² × $x = 270 ft² × $38
$x = 270 ft² × $38/ 1 ft²
$x = $10,260
Therefore, the total price for the carpeting of the room is $10,260.

A population of insects, in thousands, can be molded using the function (t)= 1.75(0.97)x
Answers
Question:
A population of insects, in thousands, can be modeled using the function
[tex]p(t) = 1.75(0.97)^t[/tex], where t is time in months. Which statement best
describes the population of insects?
A. The population is decaying at a rate of 3% each month.
B. The population is decaying at a rate of 25% each month.
C. The population is growing at a rate of 75% each month.
D. The population is growing at a rate of 97% each month.
Answer:
A. The population is decaying at a rate of 3% each month.
Step-by-step explanation:
Given
[tex]p(t) = 1.75(0.97)^t[/tex]
Required
True statement about the function
From the options, we can see that we are to answer the question on the basis of decay and growing rates.
An exponential form is:
[tex]y=ab^x[/tex]
Compare to [tex]p(t) = 1.75(0.97)^t[/tex]
[tex]b= 0.97\\[/tex]
If [tex]b > 1[/tex], then [tex]b = 1 + r[/tex] r represents growth rate
else, [tex]b= 1-r[/tex] r represents decay rate
Since b < 0.97:
[tex]0.97= 1-r[/tex]
[tex]r = 1 - 0.97[/tex]
[tex]r = 0.03[/tex]
[tex]r = 3\%[/tex]
[tex]r = 0.03[/tex]
Jasmine had $120,000 last year. This year she has $50,000
What is the percentage difference?
Answers
The percentage difference if Jasmine had $120,000 last year and this year she has $50,000 is 41.6%.
What is percentage?As it is clear from the term per cent means measuring anything per hundred. For example, you get marks per 100 marks, so you get the percentage.
Given:
The last year value = $120000,
The new value of this year = $50000,
Calculate the percentage by the following formula,
Percentage difference = The new value of this year / The last year's value ×100
Substitute value
Percentage difference = 50000 / 120000 × 100
Percentage difference = 41.6%
Therefore, the percentage difference if Jasmine had $120,000 last year and this year she has $50,000 is 41.6%.
